Abstract

A chemical additive for purifying gasoline tail gas is composed of the following raw materials in parts by weight: 30 to 40 parts of ethanol, 10 to 20 parts of m-toluic acid, 10 to 20 parts of trichloroethane, 20 to 30 parts of cyclohexanone, 20 to 30 parts of toluene, and 1 to 10 parts of trichloroacetic acid. The chemical additive is suitable for vehicle gasoline, and the mass ratio of the additive to gasoline is (1:500) to (1:2000) when in use. The chemical addictive has the advantages of available raw materials, simple technology, good stability, user-friendliness, and easy promotion. After the addition of the chemical additive, each physical or chemical index of gasoline is not influenced, at the same time the gasoline performance is improved: the combustion is complete, the carbon deposit is reduced, the discharge amount of carbon monoxide is reduced by 20% on average, the discharge amount of hydrocarbon compounds is reduced by 15% on average, so the environment protection is assisted by the chemical additive.

Description

technical field [0001] The invention relates to a chemical additive, in particular to a chemical additive for gasoline tail gas purification. Background technique [0002] Due to the quality problems of the fuel itself and the insufficiency of the mechanical manufacturing limit of motor vehicles, there will be chilling effects, gap effects, prone to knocking, intake valves, and electric nozzles. Coke deposits; waste of fuel, emissions and pollution of the atmosphere, etc. Contents of the invention [0003] In order to overcome the above-mentioned shortcoming of the prior art, the object of the present invention is to provide a kind of unleaded gasoline antiknock chemical additive, significantly improve octane number, improve oil chemical performance, have the effect of catalytic combustion, can make mixed gas fully burn, Increase the speed of fireworks, thereby reducing the occurrence of knocking, less environmental pollution, and significant economic and social benefits. ...
